How_to_Find_Supplier_Number.pdf

This is a guidance document from the Washington Suburban Sanitary Commission (WSSC) in Maryland detailing how to locate a supplier identification number in their procurement system. The document provides three steps for suppliers to find their Supplier ID: logging into the WSSC Supplier Portal, navigating to Supplier Details under the WSSC Supplier Profile & User Manager section, and locating the Supplier Number in the General header section of the portal accessible at https://www.wsscwater.com/supplier.

This guidance document is directly relevant to the Water Quality Surveillance and Response System solicitation issued by WSSC, for which sealed responses must be submitted via the WSSC eProcurement Portal at https://procurement.opengov.com/portal/wsscwater prior to 2:00 pm on Monday, October 5, 2026. The consultant services being procured will support WSSC's drinking water contamination preparedness, surveillance, and response programs under the EPA's Surveillance and Response System framework, including online water quality monitoring, customer complaint surveillance, laboratory confirmation capabilities, contaminant prioritization, risk assessment, standard operating procedures development, and training support. Work will be performed on a task order basis with individual assignments defining scope, schedule, staffing, and compensation for each task, supporting ongoing initiatives to expand monitoring capabilities and strengthen preparedness for potential drinking water contamination events.
